SLOPE = (y₂−y₁)/(x₂−x₁)
Rise over Run · direction of line
y = mx + b
m = slope · b = y-intercept (when x=0)
FLIP SIGN → FLIP < >
Multiply/divide inequality by negative → flip!
PARALLEL = SAME m
Perpendicular = NEGATIVE RECIPROCAL slope
Geometry
△ ANGLES = 180°
Sum of interior angles of any triangle
a² + b² = c²
Pythagorean theorem · right triangle only
CIRCLE: A = πr²
Circumference = 2πr · diameter = 2r
POLYGON ANGLES
Sum = (n−2) × 180° · n = number of sides
